Himmel.
The image of the large feathery creature sitting upon the fish, talons engaged and puncturing the body, was all he could think of. The shimmer of the fish scales as the water tapered off of it. The puckering of the skin where the claws dug in. Most of all, the smell - you'd expect a freshly caught thing to be clean smelling, but he could recall with perfect clarity the metallic scent of its blood. And with the innocence of youth to cushion any moral explorations, Himmel's brain sparked an idea.
He didn't prance so much as sulk towards the ponds. It was here that the bird had speared its fish (after some magical assistance); but Himmel knew he did not have that capability. He did have his pointy toes, and his limbs were long thin and easy enough to control. So he crept to the side of the ponds and dipped his head in mimicry of drinking.
He stood there, stooped, watching the water's surface. He did not touch the water. He didn't even blink if he could help it - just staring at the water and willing the fish to move. He watched the tiny shapes shimmering beneath the surface and when they drifted closer, oblivious to the danger that the herbivore might pose, and when one got close enough Himmel thrust a forelimb through the fluid like a joust with the hopes he could impale something.
